Since you are in the general asia section, I assume it can be dramas from no matter what country. :)
Here are my suggestions:
1. Don Quixote (J) - Hilarious, original, well acted, heartwarming. Although it's a bit of a closed-episodes drama, I got hooked to it and watched it almost marathon like. Adorable.
2. Material Queen (Tw) - Uncommon characters, completely anti-heroic, well acted (with the exception of some side characters) and romantic. A plus: great music.
3. I need Romance (K) - if you haven't watched it yet, I recommend it to you. It's truly refreshing for a Korean drama. It's funny, clever, with some female characters with guts and stamina. Personally, I loved it.
P.S. I am stuck on ep.13 of PTB and can't go on either. I think I'll put in on hold... indefinitely. :P
